Our friend is in the hospital.He is continually cycling in and out of consciousness every 2 minutes. His breathing cycles with his consciousness. When he awakens he gasps for air and then goes back into really shallow breathing when he falls asleep. the CO2 buildup in his blood is damaging his brain.The doctors don't understand.Any help or reference sources.When he wakes up, he pleads with me to get him out of there becauseHis wife stands to win several million dollars if he dies.Needless to say his best interests are not being followed.
